Golden Sun is an AWESOME series and the third installment is finally on its way. Old news, I know, but not even the GS community itself is passionate to make a big deal of it, except in small pockets.
If anyone here follows the series, have you any thoughts on who the fourth party member will be? So far, it looks like they will be the children of the main characters from the last two games, and possibly Isaac. That, or his son really looks exactly like him.
